Climate change 'tipping points' too close for comfort

Loading the atmosphere with five million tonnes of CO2 every hour has pushed Earth dangerously close to a no-return threshold, beyond which lies an unlivable hothouse world, top climate scientists have warned.

Toward more efficient computing, with magnetic waves

MIT researchers have devised a novel circuit design that enables precise control of computing with magnetic waves—with no electricity needed. The advance takes a step toward practical magnetic-based devices, which have ...

Underwater telecom cables make superb seismic network

Fiber-optic cables that constitute a global undersea telecommunications network could one day help scientists study offshore earthquakes and the geologic structures hidden deep beneath the ocean surface.

Additive manufacturing and Ni/Ti metal bolster cooling technology

Scientists at the University of Maryland (UMD) have developed a novel elastocaloric cooling material, comprised of a nickel (Ni)-titanium (Ti) alloy and sculpted using additive technology, that is highly efficient, eco-friendly ...
